124 BULLETIN OF THE LITHUANIAN ENTOMOLOGICAL SOCIETY. Volume 3 (31) FIRST RECORDS OF CHRYSIS SPLENDIDULA ROSSI, 1790 (HYMENOPTERA: CHRYSIDIDAE), AND OTHER CORRECTIONS OF THE CUCKOO WASP CHECK-LIST OF LITHUANIAN FAUNA SVETLANA ORLOVSKYTĖ, EDUARDAS BUDRYS Nature Research Centre, Akademijos 2, LT-08412 Vilnius, Lithuania. E-mail: [email protected] Introduction Chrysis splendidula Rossi, 1790 (Hymenoptera: Chrysididae) is a cleptoparasitic cuckoo wasp widespread in the Palearctic region ranging from Europe and North Africa to Southeast Asia (Linsenmaier, 1959, 1997; Курзенко, Лелей, 2007). It has been recorded in neighbouring countries, such as Latvia (Paukkunen et al., 2014), Belarus, Poland (Wiśniowski, 2015), while the presence of this species in Lithuania has not yet been confirmed. Moreover, some other corrections must be made in the Lithuanian check-list of chrysidids (Orlovskytė et al., 2010) due to a new species description, misidentifications, and a revised taxonomic status of some species. The aim of this publication is to present new records of this cuckoo wasp species and to adjust the Chrysididae species check-list of Lithuania. Material and Methods The material was collected during field research using entomological net and yellow pan traps by E. Budrys (abbreviated as E.B.) and S. Orlovskytė (S.O.). It was identified according to W. Linsenmaier (1997), J. Paukkunen et al. (2015) and deposited in the Nature Research Centre (Vilnius, Lithuania). Total genomic DNA of the specimen from Užuožerės Miškas f. was extracted following the "GeneJet Genome Purification Kit" (Thermo Fisher Scientific) protocol. The 675 bp long fragment of the CO1-5' gene, widely used as a "barcoding" sequence (Hebert et al., 2003), was amplified with modified primers T3HYMlep-f (5'- attaaccctcactaaagtcwachaaycayaaaratatygg-3') and T7HYMnancy-r (5'- aatacgactcactataggdaraattaraatrtaaacytcwg-3') (Budrys et al., 2019). The sequencing was performed in Macrogen Inc. (South Korea, Seul). List of localities Locality Administrative district Coordinates (LAT, LONG) Veisiejai Nat. R.

Chrysis splendidula is a robust species, characterized by the dark blue head, thorax, and the 3rd gastral tergite. It differs from the closest morphologically C. rutilans Olivier, 1791 by a broader head and gaster, coarser and denser punctuation, a distinct longitudinal keel on the 2nd tergite (Fig. 1 A), as well as by shorter black patches on the 2nd sternite (Fig. 1 B) (Linsenmaier, 1997; Paukkunen et al., 2015; Wiśniowski, 2015). The CO1-5' sequence of the studied specimen has been matched by 99.79 % to C. splendidula splendidula from Italy (Niehuis, Wägele, 2004) with Sample ID AJ514390 available in the BOLD barcoding index number (BIN) database (http://www.boldsystems.org/index.php/Public_BarcodeIndexNumber_Home). Among other species of local fauna, this species is closest to C. rutilans not only by morphological, but also by molecular characters: similarity of their CO1-5' sequence is 92.33 % in the BOLD database. Chrysis splendidula is known as a cleptoparasite of Eumenes coarctatus (Linnaeus, 1758) (Hymenoptera: Vespidae: Eumeninae) (Martynova & Fateryga, 2015). The latter wasp species constructs nests in open habitats, such as sparsely vegetated sandy areas (Paukkunen et al., 2015), psammophilic, steppic, xerophilous grasslands (Wiśniowski, 2015). A B Fig. 1. Female of Chrysis splendidula: the gaster (A), the 2nd sternite (B). The Lithuanian check-list of cuckoo wasps (Orlovskytė et al., 2010) comprised 49 species of 12 genera. In addition to Chrysis splendidula, it must be supplemented by two more species: Hedychridium zelleri (Dahlbom, 1845), detected in Lithuania for the first time in 2016 (Paukkunen et al., 2016), and a recently described C. parietis Budrys, 2016 (Orlovskytė et al., 2016). On the other hand, nominal species C. subcoriacea Linsenmaier, 1959, C. fasciata Olivier, 1790, and H. chloropygum du Buysson, 1888 must be eliminated from the check-list due to misidentifications of the taxa: a re- identification in accordance to the recent review of Northern European cuckoo wasps (Paukkunen et al., 2014, 2015) and the DNA barcoding revealed that the misidentified specimens belong correspondingly to C. longula Abeille de Perrin, 1879, C. zetterstedti Dahlbom, 1845, and H. roseum (Rossi, 1790). 126 BULLETIN OF THE LITHUANIAN ENTOMOLOGICAL SOCIETY. Volume 3 (31) Furthermore, the check-list must be adjusted due to several taxonomic changes. Chrysis ignita Form A sensu Linsenmaier, 1959 has been proved to have a valid name C. terminata Dahlbom, 1854, while C. ignita Form B sensu Linsenmaier, 1959 retained the name C. ignita (Linnaeus, 1758) (Paukkunen et al., 2014). Cleptes pallipes Lepeletier, 1806 was synonymised with C. semiauratus (Linnaeus, 1761) (Rosa et al., 2015). Pseudochrysis Semenov, 1891 has been confirmed to be a valid genus name for a group of species considered as Pseudospinolia Linsenmaier, 1951 (Rosa et al., 2017); therefore, the name Pseudospinolia neglecta (Shuckard, 1836) should be replaced by Pseudochrysis neglecta (Shuckard, 1836). According to these changes, the Lithuanian Chrysididae check-list includes 51 species. There is a high probability to expand it with species, such as Chrysis sexdentata Christ, 1791, C. subcoriacea, Cleptes nitidulus (Fabricius, 1793), Elampus constrictus (Förster, 1853), Omalus biaccinctus (du Buysson, 1892), which have not been detected in Lithuania so far, but they have been recorded in neighbouring Latvia, Belarus, and Poland (Wiśniowski, 2015).
